FIG. 1 is a perspective view of the tread for pneumatic tires incorporating my new design, it being understood that the tread pattern repeats circumferentially throughout the outer circumference.

FIG. 2 is an elevational view of one end of the tread for pneumatic tires shown in FIG. 1.

FIG. 3 is a fragmentary view of FIG. 2.

FIG. 4 is an elevational view of one side of the tread for pneumatic tires shown in FIG. 1, it being understood that the opposite side is of identical appearance.

FIG. 5 is a view similar to FIG. 3, with a section line A-A drawn therein; and,

FIG. 6 is a cross sectional view taken along the section line A-A of FIG. 5.

The broken lines in the drawings depict environmental subject matter only and form no part of the claimed design.
